The operation of any Brush DC Motor is based on electromagnetism. The Brush DC Motor has two terminals; when voltage is applied across the two terminals, a proportional speed is outputted to the shaft of the Brush DC Motor. A Brush DC Motor consists of two pieces: the stator which includes the housing, permanent magnets, and brushes, and the rotor, which consists of the output shaft, windings and commutator.

Applications:

Although the brushless DC motor has surpassed the Brush DC Motor because of its longetivity and reliability, the Brush DC Motor is still appropriately chosen for many applications. Most commonly, the Brush DC Motor is found in household applications. It can also be found in the industrial world because of its versatility in altering its torque to speed ratio.
